The painting 4050219 by Katinka Lampe is part of Bubble, a series of paintings she created during the lockdown of 2021. Separated from the world, without friends, colleagues and collectors in her studio, she felt like being contained in a bubble. Bubble is also inspired by the term filter bubble, which was coined by internet activist Eli Pariser circa 2010. According to Pariser, internet users get less exposure to conflicting viewpoints and are isolated intellectually in their own informational bubble. He warned that “invisible algorithmic editing of the web” may limit our exposure to new information and narrow our outlook. This may increase polarization and extremism.
